Question

Which of the following statements concerning food chains is not true

• A. It shows which organisms feed on which other
• B. It shows the number of each organism eaten by another
• C. Plants form the basis of food chains
• D. It shows the order in which organisms are fed upon by other

Answer 1

The correct option is B It shows the number of each organism eaten by another

A food chain is a linear network of links in a food web starting from producer organisms and ending at apex predator species, detritivores, or decomposer species. A food chain also shows how the organisms are related with each other by the food they eat. Each level of a food chain represents a different trophic level. In its simplest form, the length of a chain is the number of links between a trophic consumer and the base of the web and the mean chain length of an entire web is the arithmetic average of the lengths of all chains in a food web.

So the correct option is 'it shows the number of each organism eaten by another'.
